My brother Comets Section: Carl Hergenrother Chris and I traveled to Manitoba, Canada to view it. Under Meteors Section: Robert D. Lunsford incredible odds, adversity, and good humor, we witnessed the total solar eclipse in all its glory.

In an age where personal Youth Section: Timothy J. Robertson histories are valued by historians to learn “the story behind the story”, you too can provide a unique visualization of your experiences now and for future generations to read.
